Greece's Pneumonological Society will offer free lung function tests with the aid of a mobile spirometer on Monday and Tuesday mornings at Klafthmonos Square in central Athens, in order to mark World No Tobacco Day on May 31.
The testing will be conducted between the hours of 9:30 a.m. and 2:30 p.m. on both days.

A spirometry test essentially measures how well one breathes and can help in the diagnosis of various respiratory ailments, such as asthma, pulmonary fibrosis and others. The test is painless and usually lasts about five minutes.
